It will of coursebe understood from vthe .foregoing description that inoperation both driving shafts are rotated in the ksame'directheoperation of the motor but with an intermittent motion since the drivingshaft 1,00 is only Vrotated while the belt v90 is'being drawn oifthedrum by the movement of the lay in one direction but as at eachreciprocation of the lav Vbut a single loop isy added to the fabric anda single loop inturn forced against each cutter, the latter, eventhoughv driven intermittently, are entirely effective to perform thecutting opera# tion.

Additionally, by the employment of a plu- 1ality of series of cutters inwhich the cutters spaces between the cutters in the other series, amenabled to produce a machine which will operateefliciently on thoseclasses of fabrics in which the. rows ofweft loops or floats are spacedvery closely together and which it would be impossible to cutsatisfactorily in vmachines-in which the cutters are Varranged in asingle row or series by reason of the inherent and necessary thicknessofthe cutters themselves which prevents their being placed sufficientlyclose together to operate on fabrics of this character.

While have herein -described'-with considerable particularity apreferred embodiment of my invention and have described its operationinV connection with av loom in fabric are formed over pile wires, itwill befnnderstood that Vthe invention may be'uscd with located inalignment with the Y equal facility in connection with other forms ofleaders and in the production of various classes and sorts of fabrics,andadditionally, thatth various elements of the machine and theconstruction, design and arrangement thereof may vbe vmodified from theprecise embodiment shown without departing from the spirit and scope ofthe invention as defined in the appended claims.
